Diamond Anatomy

Diameter: this is the width of a polished and finsihed diamond measured from edge to edge Table: This refers to the largest polished facet located on the top of the diamond Crown: This refers to the top of a diamond extending from the table to the girdle Girdle: This refers to the very edge of the diamond where the crown and pavilion meet Pavilion: This refers to the bottom part of the diamond extending from the girdle down to the cutlet. Depth: This refer to the total height of a diamond measured from the table to the cutlet. Cutlet: This refer to the small or pointed facet at the very bottom of a polished stone.

Diamond Cut Proportions

	If a diamond is cut too shallow this is how the light will travel through the diamond. Entering light strikes the pavilion facet at a low angle and passes through the facets, escaping through the bottom of the diamond.
	If a diamond is cut too deep this is how the light will travel through the diamond. As the light strikes the first pavilion facet at an angle shapr enough to reflect to the second pavilion. But the light strikes the second pavilion at too low an angle, causing the light to refract and pass through the facets, it then escapes through the bottom part of the diamond.
	If a diamond is well cut this is how the light will travel through the diamond. The light strikes each pavilion facet at an angle which allows most of the light to reflect back to the crown. As it passes through the crown facets at a low angle, the light refracts upon exit. In this case, refraction is a good thing, as the bent light travels to the observer's eye and is perceived as a lively fire.

Diamond Cut Grades

Excellent- this is the best grade cut that is achievable. Diamonds with this cut have maximum fire and brilliance. The diamond reflects nearly all of the light that enters the diamond, creating exceptional sparkle and fire.
Very Good- diamond with this cut reflects most of the light that enters the diamond. It produces superior fire and brilliance. Under normal lighting conditions, appears very similar to excellent cut but for a lower price.
Good- diamonds with this cut reflect a majority of the light that enters the diamond, for an above average appearance. An excellent value compared to higher cuts.
Fair- diamonds with this cut allow much of the light entering the diamond to escape from the sides or bottom, reducing perceived fire and brilliance. More acceptable in diamond of less than .75 carats, where differences in sparkle are more difficult to perceive.
Poor – diamond with this cut allow most of the light entering the diamond to escape from the sides or bottom. The diamond may appear noticeably dull and lifeless, even to en untrained eye. We do not offer any diamond that have a poor cut.
